Pasadena, CA – NASA says the European Space Agency’s Euclid mission, set to launch in 2022, will investigate two of the biggest mysteries in modern astronomy: dark matter and dark energy. A team of NASA engineers recently delivered critical hardware for one of the instruments that will fly on Euclid and probe these cosmic puzzles.
Based at NASA’s Jet Propulsion Laboratory in Pasadena, California, and the Goddard Space Flight Center in Greenbelt, Maryland, the engineers designed, fabricated and tested 20 pieces of sensor-chip electronics (SCEs) hardware for Euclid (16 for the flight instrument and four backups).
Washington, D.C. – On Saturday, July 20th, 2019, at NASA’s Kennedy Space Center in Florida, Vice President Mike Pence gave remarks in the Neil Armstrong Operations and Checkout Building to commemorate the 50th anniversary of the agency’s Apollo 11 Moon landing and announce to America the completion of NASA’s Orion crew capsule for the first Artemis lunar mission.
“Thanks to the hard work of the men and women of NASA, and of American industry, the Orion crew vehicle for the Artemis 1 mission is complete and ready to begin preparations for its historic first flight,” said Vice President Pence.

Pasadena, CA – While headlines routinely report on “close shaves” and “near-misses” when near-Earth objects (NEOs) such as asteroids or comets pass relatively close to Earth, the real work of preparing for the possibility of a NEO impact with Earth goes on mostly out of the public eye.
For more than 20 years, NASA and its international partners have been scanning the skies for NEOs, which are asteroids and comets that orbit the Sun and come within 30 million miles (50 million kilometers) of Earth’s orbit.
Washington, D.C. – The powerhouse that will help NASA’s Orion spacecraft venture beyond the Moon is stateside. The European-built service module that will propel, power and cool during Orion flight to the Moon on Exploration Mission-1 arrived from Germany at the agency’s Kennedy Space Center in Florida on Tuesday to begin final outfitting, integration and testing with the crew module and other Orion elements.
The service module is integral to human missions to the Moon and Mars. After Orion launches on top of the agency’s Space Launch System rocket, the service module will be responsible for in-space maneuvering throughout the mission, including course corrections.
NASA’s Hubble Space Telescope, European Space Agency’s Gaia Space Observatory Measure the Universe’s Expansion Rate
Space Telescope Science Institute
Baltimore, MD – Using the power and synergy of two space telescopes, NASA says astronomers have made the most precise measurement to date of the universe’s expansion rate.
The results further fuel the mismatch between measurements for the expansion rate of the nearby universe, and those of the distant, primeval universe — before stars and galaxies even existed.
This so-called “tension” implies that there could be new physics underlying the foundations of the universe. Possibilities include the interaction strength of dark matter, dark energy being even more exotic than previously thought, or an unknown new particle in the tapestry of space.

Pasadena, CA – Ice losses from Antarctica have tripled since 2012, increasing global sea levels by 0.12 inch (3 millimeters) in that timeframe alone, according to a major new international climate assessment funded by NASA and the European Space Agency (ESA).
According to the study, ice losses from Antarctica are causing sea levels to rise faster today than at any time in the past 25 years. Results of the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE) were published Wednesday in the journal Nature.

Washington, D.C. – Researchers using NASA’s Mars Reconnaissance Orbiter (MRO) have found eight sites where thick deposits of ice beneath Mars’ surface are exposed in faces of eroding slopes.
These eight scarps, with slopes as steep as 55 degrees, reveal new information about the internal layered structure of previously detected underground ice sheets in Mars’ middle latitudes.
The ice was likely deposited as snow long ago.

Washington, D.C. – NASA has selected two finalist concepts for a robotic mission planned to launch in the mid-2020s: a comet sample return mission and a drone-like rotorcraft that would explore potential landing sites on Saturn’s largest moon, Titan.
The agency announced the concepts Wednesday, following an extensive and competitive peer review process. The concepts were chosen from 12 proposals submitted in April under a New Frontiers program announcement of opportunity.
New Study using NASA’s Cassini Spacecraft data reveals heat from friction may power Hydrothermal Activity on Saturn’s Moon Enceladus
Written by Preston Dyches
Pasadena, CA – Heat from friction could power hydrothermal activity on Saturn’s moon Enceladus for billions of years if the moon has a highly porous core, according to a new modeling study by European and U.S. researchers working on NASA’s Cassini mission.
The study, published today in the journal Nature Astronomy, helps resolve a question scientists have grappled with for a decade: Where does the energy to power the extraordinary geologic activity on Enceladus come from?

Washington, D.C. – An international team of astronomers led by NASA scientists successfully completed the first global exercise using a real asteroid to test global response capabilities.
Planning for the so-called “TC4 Observation Campaign” started in April, under the sponsorship of NASA’s Planetary Defense Coordination Office. The exercise commenced in earnest in late July, when the European Southern Observatory’s Very Large Telescope recovered the asteroid. The finale was a close approach to Earth in mid-October.
